عن أنس قال إن إمرأة أتت النبي ﷺ فقالت يا رسول الله إمسح وجهي وادع الله عز وجل لي قال فمسح ﷺ وجهها ودعا الله تعالى لها قالت يا رسول الله سفّل يدك فسفل ﷺ يده على صدرها فقالت يا رسول الله سفل يدك فأبى ﷺ وباعدها

From Anas who said: A woman came to the Prophet (SAW) and said: Oh Messenger of Allah, wipe my face and call on Allah Mighty and Sublime for me. So He (SAW) wiped her face and called on Allah Most High for her. And she said: Oh Messenger of Allah, lower your hand. And He (SAW) lowered his hand onto her chest. And she said: Oh Messenger of Allah, lower your hand more. But He (SAW) refused and moved her away.
